Light

A light shape is a shape that is not solid or strong, but cannot easily be attacked because one is able to sacrifice a part of it, thus using the opponent's attack to strengthen oneself. Apart from the willingness to sacrifice, there should also be an element of flexibility - depending on where the opponent attacks, either one part gets sacrificed and the other strengthened, or the other way around.

A light stone is one that is easily sacrificed, because the opponent will not have gained much when he captures it. This is for example the case if the opponent has already answered the stone - if he next captures it, it means he has answered the stone two or three times. To try to save a stone that is light, is a heavy way of playing.
